Here is the poster:

Translation:
“Give us something to drink. We are dying of thirst.
“Thousands of street cats die of thirst every summer. A water dish in the yard saves lives
It is enough to put a large plastic container in a corner of the yard and fill it with water once a day, or else place it underneath the dripping hose of an air conditioner. They will be thankful and your heart will be filled with joy and satisfaction. Thanks.”

What a good poster!
There is always a bowl of fresh water in our garden, not only for thirsty cats passing through but for hedgehogs and wild birds too.
It takes so little effort to make life a little bit better for any creatures we can.
Here in the Phoenix Metropolitan area, we can’t leave water out for to long because of our mosquito laws. Our mosquito’s sometimes carry malaria and the West Nile virus, so standing water is not allowed. Luckily we have several small man made lakes and tons of sprinklers to compensate. Water dishes are acceptable, of course, I guess it would depend on the container and how close it was to your house. A pan in the vacant lot would be a problem.
It is something people don’t naturally think of. In Britain, stray cats don’t have the same water problems because it is much cooler. Food is the problem.
Wow! That is an amazingly good idea. I hope many readers follow through.
All I know is that there are lots of stray and feral cats in Israel. I suppose therefore that there are lots of thirsty cats.
What is the situation like in the Middle East for domestic, stray and feral cats? Do you know? Are there lots?
The situation is much worse in countries like Saudi Arabia, Dubai, etc. where temperatures are hostile to all forms of life. I did not find Israel all that hot but as soon as you enter the Gulf you are in a furness.
